【摘要】 根据柴达木地块获得的6个古地磁数据,结合已知的古地磁数据阐述了柴达木地块及与相邻板块间的演化模式.结果表明柴达木地块从震旦纪到石炭纪一直处于赤道附近和低纬度地区.石炭纪时,柴达木、杨子及走廊过渡带三地块均处在赤道附近,三者可能是连在一起的.而华北板块与上述三地块至少有10°左右的纬向差,因此,华北与柴达木、杨子和走廊过渡带当时还没有连在一起.更多还原

【Abstract】 The paper illuminates evolution model of Chaidam plate and adjacent plates on the basis of six palaeomagnetic data from chaidam and combining known palaeomagnetic data. The result indicates that Chaidam plate located close to the dquator and in the low Latitude region from the Sinian peried to the Carboniferous period. Chaidam, Yangtze and Corridor transit zone located all close to the dquator in the Carboniferous period, three plates might be connected together, but palaeolatitude difference is at least 10° or so between North China plate and above-mentioned three plates, for this period, North china was not connected together with Chaidam, Yangtze and Corridor transit zone at that time.更多还原
